Reduction of erosion rates for steam operations through nanocoatings

AP Dynamic Inc.专注于计算流体动力学(CFD)、扭转振动、管道应力、脉动和侵蚀缓解以及机械设计等领域。目前的挑战之一是，由于蒸汽流动中存在水滴，一次过热回收蒸汽发生器(OTSGs)管道的腐蚀。为了缓解这一问题，需要一种预测性的方法来估计材料损失，以便计划预防性维护并最大限度地提高采油过程中的蒸汽产量。此外，为了提高蒸汽管道的寿命，需要减少腐蚀。本项目的主要目标是开发一个模型来预测蒸汽管道的冲蚀速率，并提出一种基于纳米颗粒的纳米涂层来提高抗冲蚀性能。为了研究蒸汽喷射在管道内造成的侵蚀率，AP Dynamic和卡尔加里大学建立了合作关系，设计、制造、优化和测试了一套模拟带有集成传感器的蒸汽喷射系统的装置。在该系统中，将通过对管道内表面的冲击进行动态分析，来测量影响管道内表面冲蚀率的未知经验参数。为了减轻腐蚀，将在钢管型材上应用纳米涂层。蒸汽侵蚀试验的金属衬底将通过各种显微技术进行表征，所开发的系统将用于对不同的蒸汽喷射速度、液滴大小、流体等对裸钢管和涂层钢管的影响进行全面的实验研究。该项目的成果将使AP Dynamic能够开发一个模型来预测和分析蒸汽管道的侵蚀，并防止灾难性的故障。与常规管道相比，所开发的纳米涂层可以产生具有更高耐腐蚀性的保护层。研究结果将使HQP的培训成为可能，并为AP Dynamic在分析和预防蒸汽管道冲蚀故障方面提供竞争优势。

AP Dynamics Inc. specializes in the fields of computational fluid dynamics (CFD), torsional vibrations, pipingstress, pulsation and erosion mitigation, and mechanical design. One of the current challenges is the erosion inOnce Through Heat Recovery Steam Generators (OTSGs) piping due to water droplets existing in the flow ofsteam. To mitigate the problem, a predictive approach is required to estimate the material loss in order to planpreventive maintenance and maximize steam productions in oil extractions. Furthermore, the reduction oferosion is needed to enhance longevity of steam pipes.The main goal of this project is the development of a model to predict the erosion rates in the steam pipes andpropose a nanocoating based on using nanoparticulates for enhancing erosion resistance. To investigate theerosion rate caused by the steam jet within the pipes, AP Dynamics and the University of Calgary have formeda collaborative relationship to design, manufacture, optimize, and test a setup to mimic the steam jet systemwith integrated sensors. In the proposed system, the unknown empirical parameters influencing the erosion rateof the internal surface of the pipes will be measured through dynamic analysis of the impacts on the internalsurface of the pipes. To mitigate the erosion, the nanocoating will be applied to steel pipe sections. The steamerosion tested metallic substrates will be characterized via a various microscopy techniques.The developed system will be used for performing a comprehensive experimental investigation on the effectsof different steam jet velocities, droplet sizes, fluids, etc. on bare and coated steel pipes. The outcomes of theproject will enable AP Dynamics to develop a model to predict and analyze the erosion in steam pipes andprevent catastrophic failures. The developed nano coatings can result in protective layers with higher erosionresistance values compared to the regular pipes. The outcomes of the research will enable training of HQP andprovide a competitive edge for AP Dynamics for analyzing and preventing erosion failures in steam pipes.
